Cryptography is faster on a GPU than a CPU, if it is programmed. It is faster on an ASIC than a GPU, but to do that the algorithm that has to be programmed and designed / manufactured in hardware.

Feathercoin deliberately moved to Neoscrypt cryptographic alogorythm because it takes more memory to run than the Bitcoin or Litcoin ASICs, and therefore could only be run on a CPU. Feathercoin did not move to Neoscrypt until a GPU version was programmed, in this case paid for by FTC admin (@Calum).

One of the basic things about Bitcoin based cryptocurrencies is they are deflationary.

That is the amount of currency gradually decreases, not increases like the inflation or gradual easing of Fiat currency.

Fiat currency is legal tender whose value is backed by the government that issued it. The U.S. dollar is fiat money, as are the euro and many other major world currencies. This approach differs from money whose value is underpinned by some physical good such as gold or silver, called commodity money

One ways Crypto currencies are deflationary is by having the value of the mining fee every so often, in FTC case, 4 years. This is input into the code to occur at a certain block number. In practice, the block times are only approximate, depending on the number of miners / hash rate. Variation in hash rate can only be corrected for afterwards, which will tend to delay the halving beyond exactly 4 years.
